CUTTER FOR PAPER-BOX-COVERING MACHINES.

SPECIFICATION forming part of Letters Patent No. 348,000, dated August24-, 188 I.

Original application, No. 167,-951, filed June 8, I885. Divided and thisapplication filed May 15, 1886. Serial No. 102,270.

(No model.)

To all whom it may concern:

Be it known that I, ANDREW M. EASTMAN, of Milford, in the county of\Vor'cester and State of Massachusetts, have invented certain new anduseful Improvements in Machines for Covering Paper Boxes, of which thefollowing, taken in connection with the accompanying drawings, is aspecification.

My present invention is a division of another application filed by me inthe Patent Office at Washington, June 8, 1885, No. 167,951, and relatesespecially to the paper-severing devices and the means of operating thesame; and it consists in certain novel features of con struction,arrangement, and combination of parts, which will be best understood byreference to the description of the drawings, and

' to the claims to be hereinafter given.

Figure 1 of the drawings is a perspective of a machine embodying myinvention. Fig. 2 is a plan of the paper-cutting mechanism removed fromthe machine. Fig. 3 is a sectional elevation of the same, thecuttingplane being on line av 00 on Fig. 2, and Fig. 4 is a trans versesection through the weighted arm of the upper shear-blade and thecam-lever by which box-carrying form at the completion of eachrevolution, all of the foregoing parts being constructed, arranged,andoperated substantially as shown and described in detail in theabove-mentioned application, and therefore require no furtherdescription here.

Upon one end of the shaft 6 is secured the driving-pulley c, and uponthe opposite end thereof has loosely mounted the arm f, the hub of whichis provided With'theperipheral groove 5 f, and with clutch-teeth toengage with corresponding teeth on the hub or collar f firmly securedupon the shaft 6.

A horizontal shipper-rod, h, is mounted in suitable bearing 011 thelower side rail of the frame, and is provided with upwardlyprojectingarms h h, which engage with the groovef and with the pendentarm If,extending nearly to the floor in a position to be moved about the axisof the rod h by the pressure of the operators foot to cause the twoparts of the Iclutch to engage and the arm fto revolve with the shaft 6.

Upon the front end of one of the upper side rails of the'frame is firmlysecured the stand 9, to the upper end of which is secured in an inclinedposition the frame E, provided upon its upper side with the ribs 2' i,between which is fitted, so as to be adjustable in the direction ,of thelength of the machine, the frame F, pro.- vided upon its upper side withthe upwardly- "projecting ribj, in the upper edge of which is formed thelongitudinal groove 2', in which is is fitted, so as to be movableendwise therein, the lower shear-blade, G, from which projects laterallythe pin 7;, to which one end ofa chain, 1, is connected,said chainpassing overthe sheave or pulley Z, mounted upon the shaft m, having itsbearings upon the frame E, and having its other end secured to the freeend of the arm f,

spur-pinions pp' and the lifter-arm 19 having a portion of its lengthmade withian inclined side to serve as a cam to act upon the inclinedsurface of the shouldered lug p", secured to the upper shear -blade, G,which is also fittedloosely upon the shaft 19, and provided at its lowerend with the counter-weight pies shown.

The ends of the shaft 12 project into the slots 0 in the ribs a a,toprevent the shear-blades and the shaft 1) being lifted so as todisengage the pinions p p from the racks n a.

The frame F may be secured in any desired position on the frame E bymeans ofthe clamps q q and screws q q. (Shown in Figs. 2 and 3.)

The operation of my invention is as follows: The several parts of themachine being ad ICO justed to the job in hand,and the box to be coveredbeing placed upon the form, and the paper 13 from the roll mounted uponthe shaft a being drawn forward and secured by its end to one end of thebox-bottom, as shown in Fig. 1, the operator presses the pendent lever houtward with his left foot, when the two parts of the clutch will beengaged and the arm f will revolve with the shaft 0, and,pulling downupon the chain 1, moves the shear-blades endwise toward the web ofpaperB until the same is fairly between the blades,when theinclined sideof the arm p comes in contact with the inclined surface of theshouldered lug p, and, by pressing said lug with the rear arm of theupper shear blade, G', away from the lower blade, G, causes the forwardor cutting arm of said blade G to be pressed into close shearing contactwith the blade G, and at the same time the blade G is moved about itsaxis to sever the paper. When the cutting of the paper has beenaccomplished, the foot of the operator is removed from contact with thependent arm h", allowing the spring r to react and cause the separationof the two parts of the clutch, when the shear-blades will be moveddownward by the force of gravity acting thereon until they reach theposition shown in Fig. 1. When a different sized box is to be covered,the shear blades are adjusted to the proper position to cut the paper ofthe desired length by loosening the screws (1 (1, moving the frame Fupon the frame E to the right or left, as the case may require, and thenti htening said screws again.

The paper-severing devices herein described and claimed are shown anddescribed in the beforementioncd application No. 167,951, of which thisis a division, but is not claimed therein.

What I claim as new,and desire to secure by Letters Patent of the UnitedStates, is-

1. In a machine for covering paper boxes, a paper-severing mechanismcomposed of a non-vibrating shear-blade fitted to and movable endwisc ina grooved track toward and from and at right angles to the line of draftof the paper to be cut, a vibrating shearblade pivoted to saidnon-vibrating shearblade, mechanism, substantially as described, formoving said shear-blades to and from the paper to be cut, with a bladeupon either side thereof, and mechanism for vibrating one of said bladesat the proper time to sever the paper.

2. In a machine for covering paper boxes, a cutting-off mechanismcomposed of a nonvibrating shear-blade having loosely mounted in abearing therein ashaft,a second shearblade loosely mounted upon saidshaft, and a lifting arm firmly secured upon said shaft and adapted toengage with and vibrate said. second blade when said shaft is movedabout its axis.

3. The combiuation,in a machine for covering paper boxes, of anon-vibrating shearblade, a vibrating shear-blade pivoted therea to by ashaft fitted loosely to both of said blades, a lug secured to saidvibrating blade and having an inclined or camsnrface, and a lifting-armfirmly secured upon said shaft, and provided with an inclined or camsurface arranged to engage with the cam-surface of said lug as the shaftis revolved and cause said shear-blades to be pressed laterally togetherwhile they are moving toward and past each other.

4. The combination,in a machine for covering paper boxes, of a pair ofshear-blades pivoted together by a loose shaft fitted therein, aspur-pinion secured upon said shaft, a rack to engage with said pinion,a track for guiding said blades in their endwise movements, a lifter-armfirmly secured upon said shaft and provided with a eam-surface near itsfree end, a cam-shouldered lug and a weight secured to the outer arm ofthe upper of said blades, and a mechanism, substantially as described,for moving said blades endwise to their highest position, and therebycausing a rotation of said shaft and of the lifter-arm and a closing ofsaid blades to sever the paper.

5. In combination with a pair of shearblades arranged to be movedendwise to and from the paper to be cut and to be vibrated to sever thepaper, the frame F, provided with the grooved track j i, and adjustableupon the stationaryframe E in a direction at right angles to the endwisemovement of said blades.

6. The combinatiomin a machine for covering paper boxes,of the fixedframe E, the laterally-movable frame F, provided with the racks n, andthe grooved track j i, the nonvibrating blade G, the vibrating blade G,provided with the cam-shaped lug p, the shaft p, the pinions p'p, thecam-lifter arm p, the pulley l, the drivingshaft e, the clutch f, thearm f, and the shipper h h h h, all constructed, arranged, and adaptedto operate substantially as and for the purposes described.

In testimony whereof I have signed my name to this speeification,in thepresence of two subscribing witnesses, on this 13th day of May, A. D.1886.

ANDREW M. EASTMAN.
